Anchor boom



March 26, 1963 F. c. GOOD ANCHOR BOOM Filed Jan. 5, 1960 INVENTOR Fred, C6006 Pa,mm d M ATTORNEYS United States Patent 3,082,730 ANCHOR BOOM Fred C. Good, 541 W. Glenwood Ave., Philadelphia, Pa. Filed Jan. 5, 1960, Ser. No. 635 2 Claims. (Cl. 114210) This invention relates to anchor booms and more particularly to anchor supporting and securing devices of the type which are particularly adapted for use on boats in the so-called pleasure craft range of sizes.

The problems in connection with the handling of small boats and the lowering or raising of anchors particularly in rough seas are Well known. Such problems are discussed in my prior US. Patent No. 2,870,732 of January 27, 1959.

The present invention, while adapted to the same usage as the anchor boom shown in the aforementioned patent, finds primary utility in the smaller size of boats of the pleasure class. The anchor boom of the aforementioned U.S. patent, on the other hand, is primarily adapted for the upper range of sizes of the pleasure boat class.

It is a principal object of the present invention to provide an anchor receiving and storing boom which is simple in construction and easily removably attached to the fore deck of a boat.

A further object of the present invention is to provide an anchor boom arrangement which will keep the anchor clear of the hull during both raising and lowering operations.

A still further object of the present invention is to provide an anchor boom of the type which, when the anchor is fully raised, will receive the anchor stem within the structural boundaries of the boom in such position that the anchor fiukes abut the outer end of the boom and the stem lies within the boom proper.

It is yet a further object of the present invention to provide a novel and useful means for detachably mounting the boom on the fore deck of a boat in order that it may be positively secured and yet easily released in order to store the anchor and boom assembly whenever desired.

Other objects of the present invention will be apparent from a consideration of the following detailed description when read in conjunction with the attached sheets of drawings in which FIG. 1 is a side elevation of the boom assembly together with a means for detachably securing the boom to the fore deck of a boat;

FIG. 2 is a perspective view of the rear portions of the boom proper;

FIG. 3 is a perspective view of that portion of the assembly which is permanently attached to the boat; and

FIG. 4 is a top plan view of the boom and the attaching member.

In general, the objects of the present invention are achieved by providing an elongated boom structure which is substantially channel shaped in cross section with the outboard ends of the upstanding channel walls diverging from each other and the corresponding web portion being cut away to provide a housing for a roller member of particular configuration. The portion of the assembly which is rigidly attached to the boat and which serves as the detachable locking means for securing the boom to the boat is also a channel shaped member of slightly larger cross-sectional dimensions than is the boom proper.

Referring now to the drawings for a detailed description of the present invention, the anchor boom is indicated generally by the reference numeral 10. The rear portion of the boom as shown in detail in FIG. 2 is substantially channel-shaped in cross section including upstanding wall portions 11 and 12 and a connecting web portion 13. As shown mos-t clearly in FIG. 4, the upstanding wall portions 11 and 12 diverge from each other at the outboard end of the boom assembly and the web portion 13 is cut away at a point corresponding to the divergence to provide a substantial opening for reception of a roller member 14. The roller member 14 is, of course, ro-tatably mounted on an axle which extends between and through the divergent portions of the sidewalls 11 and 12.

Also, as shown most clearly in FIG. 4, the roller 14 includes a center cylindrical section 15 and a pair of outer larger diameter cylindrical sections 16 and 17 and the aforementioned sections are joined by smoothly tapering surfaces 18 and 19 for reasons which will be apparent hereinafter.

Referring again to FIG. 1, it will be seen that the upstanding sidewalls 11 and 12 at the outboard end of the boom not only diverge from each other but are also turned downwardly to provide a downwardly facing abutment 20. When the anchor is fully raised, the anchor flukes will abut against the abutment 2i Four lugs 21, 22, 23 and 24 are arranged two on each side of the rear of the boom and function in cooperation with the base plate member in a manner to be hereinafter described. Referring now to FIG. 3, the supporting plate member generally indicated by the reference numeral 30 is also channel-shaped in cross section. As will be apparent from a consideration of FIG. 4 which shows the boom and the plate member in assembled relation, the cross-sectional dimensions of the member 30 are somewhat larger than those of the corresponding portion of the boom. The general cross-sectional configuration remains that of a channel member, however, including a pair of side wall members 31 and 32 interconnected by a web portion 33. At the forward end of the sidewalls 31 and 32 and adjacent the interconnecting web 33 are formed a pair of notches 34- and 35 for the reception of outwardly extending lug members 21 and 22 of the boom. At the rear of the upstanding walls 31 and 32 and again adjacent the interconnecting web 33 are formed a second pair of notches or slots 36 and 37 adapted to receive the lugs 23 and 24 of the boom. Pivotally mounted immediately ahead of the notch 37 is a small catch member 38. A pin 39 limits the upward extent of travel of the pivoted member 38, but the amount of movement provided is sufiicient to permit the insertion and removal of the boom from the base member when the base member is rigidly attached to the foredeck of a boat as for example by bolt members 40 shown in FIG. 1.

In operation, therefore, the supporting base membershown in FIG. 3 is rigidly attached to the fore deck of a boat and the boom proper is then maneuvered to position the lugs 23 and 24 within slots 36 and 37. The latch member 33 is pivoted upwardly during this procedure to allow the lugs 23 and 24 to penetrate the full depth of slots 36 and 37. With the parts in this position, the lugs 21 and 22 can be lowered over the end of the base member. The boom is then slid rearwardly until the lugs 21 and 22 abut the base of the slots 34 and 35. The latch member 38 is then moved to the position as shown in FIGS. 1 and 3, and will prevent removal of the boom from the base until the latch member is pivoted out of the way. Once the anchor has been fully raised so that the stem lies within the boom assembly and the fiukes are abutting the downwardly extending portion 20 of the boom, the latch may then move upwardly and the boom slid forwardly to enable the lugs 21 and 22 to be swung clear of the base member. The boom and anchor together may then be slid backwardly to free the lugs 23 and 24 from their slots 36 and 37 respectively and the entire assembly stored below in an appropriate location.

During raising operations, the particular configuration of the roller member 14 becomes important. Usually the anchor has a ring attached to the upper end of the stem to form a convenient means for attaching the anchor line. Furthermore, the ring is generally so arranged with respect to the anchor that when the line is taut, the ring lies in a plane substantially parallel to the anchor fiukes when they are pivoted against the stem. As the ring engages the roller 14 therefor, the anchor line tension urges the ring into .full engagement with the large diameter portions of the roller, 16 and 17. This insures that the anchor stem is guided over the small diameter center portion 15 and held in that position by the tapering surfaces 18 and 19. The stem upon further upward movement slides into the rear channel section of the boom until the fiukes abut the downwardly turned portion 20 of the boom. This same roller configuration is also helpful in preventing the line from walking up over the side walls of the boom during either anchor lowering or raising operations.

Pivotally mounted to the side Walls of the boom at the outboard end thereof is a safety ring 40 which serves a double purpose. First of all, if the anchor boom is accidentally dropped overboard, it can be retrieved because the ring will retain it on the anchor line. Secondly, is the event that the operator fails to shut off the winch when the anchor is fully raised, the ring 40 positively prevents the anchor from flying up over the end of the boom and damaging the windshield or other parts of the boat.

From the foregoing, it will be apparent to those skilled in the art that there is herein shown and described a new and useful anchor handling apparatus. While a preferred embodiment has been herein shown and described, applicant claims the benefit of a full range of equivalents within the scope of the appended claims.

I claim:
